A and C is almost correct! Lees designed the instrument panel and the complicated shelf assy between the panel and firewall which carries the AHRS, ADC, autopilot pitch computer and a few minor peripherals. Flight Composites produced and installed the magentometer bracket which is mounted 1/2 span in the starbaord wing, and they also arranged wooden mounts in the aft fuselage for the emergency attitude battery and traffic processor and fitted a nylon conduit in the starboard wing to support the wire harness. Lees draw and approved the Flight Composites work as part of the EASA STC. The instrument panel fabrication was farmed-out to a specialist sheet metal shop who also dealt with paint match and silk-screen printing - far better than the sticky labels on the factory-standard panel.
Panel layout has to conform to guidance in FAA AC23-1311-1b so this dictates the position of standby instruments. 2" versions were used as insufficient panel space was available for standard 3" instruments when an autopilot is fitted. Options exist for non-autopilot aircraft to retain the original instruments as standbys, which will reduce the cost significatly.
The customer wanted 2" standbys in the glareshield in a horizontal arrangement but this wasn't possible due to existing structure constraints.
The aircraft will be on show with Mistral Aviation/SJ Aviation at the Goodwood Festival of Speed aviation event and you can meet us there as well!
